Description

The present invention provides compounds of Formula (I), compositions thereof, and a method of antagonizing the NK-1 subtype of tachykinin receptor that comprises administering to a patient in need thereof an effective amount of a compound of Formula (I). In addition, the present invention relates to processes for preparing the compounds of Formula I and intermediates thereof.

Tachykinins are a family of peptides that are widely distributed in both the central and peripheral nervous systems. These peptides exert a number of biological effects through actions at tachykinin receptors. To date, three such receptors have been characterized, including the NK-1, NK-2, and NK-3 subtypes of tachykinin receptor.

The role of the NK-1 receptor subtype in numerous disorders of the central nervous system and the periphery has been thoroughly demonstrated in the art. For instance, NK-1 receptors are believed to play a role in depression, anxiety, and central regulation of various autonomic, as well as cardiovascular and respiratory functions. NK-1 receptors in the spinal cord are believed to play a role in pain transmission, especially the pain associated with migraine and arthritis. In the periphery, NK-1 receptor activation has been implicated in numerous disorders, including various inflammatory disorders, asthma, and disorders of the gastrointestinal and genitourinary tract.

There is an increasingly wide recognition that selective NK-1 receptor antagonists would prove useful in the treatment of many diseases of the central nervous system and the periphery. While many of these disorders are being treated by new medicines, there are still many shortcomings associated with existing treatments. For example, the newest class of anti-depressants, selective serotonin reuptake inhibitors (SSRIs), are increasingly prescribed for the treatment of depression; however, SSRIs have numerous side effects, including nausea, insomnia, anxiety, and sexual dysfunction. This could significantly affect patient compliance rate. As another example, current treatments for chemotherapy-induced nausea and emesis, such as the 5-HT3 receptor antagonists, are ineffective in managing delayed emesis. The development of NK-1 receptor antagonists will therefore greatly enhance the ability to treat such disorders more effectively. Thus, the present invention provides a class of potent, non-peptide NK-1 receptor antagonists, compositions comprising these compounds, and methods of using the compounds.

This invention includes the pharmaceutically acceptable salts of the compounds of Formula I. A compound of this invention can possess a sufficiently basic functional group, which can react with any of a number of inorganic and organic acids, to form a pharmaceutically acceptable salt.

The term “pharmaceutically-acceptable salt” as used herein, refers to a salt of a compound of the above Formula I. It should be recognized that the particular counterion forming a part of any salt of this invention is usually not of a critical nature, so long as the salt as a whole is pharmacologically acceptable and as long as the counterion does not contribute undesired qualities to the salt as a whole.

The compounds of Formula I and the intermediates described herein form pharmaceutically-acceptable acid addition salts with a wide variety of organic and inorganic acids and include the physiologically-acceptable salts which are often used in pharmaceutical chemistry. Such salts are also part of this invention. A pharmaceutically-acceptable acid addition salt is formed from a pharmaceutically-acceptable acid, as is well known in the art. Such salts include the pharmaceutically acceptable salts listed in Journal of Pharmaceutical Science, 66, 2-19 (1977), which are known to the skilled artisan.

The present invention contemplates all stereoisomers, enantiomers, and mixtures of enantiomers, including racemates and diastereomers. It is preferred that the compounds of the invention containing chiral centers are single enantiomers.

As the following schemes, preparations, and examples demonstrate, many of the compounds of the present invention are not only selective NK-1 receptor antagonists, but are also useful intermediates for the preparation of additional compounds of Formula (I). It will be recognized by one of skill in the art that the individual steps in the following schemes may be varied to provide the compounds of Formula (I).

When X of Formula (1) is a hydroxyl group, the alcohol of Formula (1) is mixed with an organic base, typically at approximately 8-12 molar equivalents of organic base per molar equivalent of the alcohol. Suitable organic bases may include triethylamine, diisopropylethylamine, pyridine, collidine, lutadine, or 1,8-diazabicyclo[5,4.0]undec-7-ene, with pyridine being the preferred base. A suitable sulfonylating agent, such as p-toluenesulfonyl chloride, methanesufonyl chloride, p-nitrobenzenesulfonyl chloride, or trifluoromethanesulfonic anhydride, preferably p-toluenesulfonyl chloride, is added in the reaction of step a for the conversion of the hydroxy group of Formula (1) into a suitable leaving group. Typically, the sulfonylating agent is used in slight molar excess to the alcohol of Formula (1).

Azide sources such as NaN3, LiN3, or tetrabutylammonium azide (Bu4NN3) are acceptable, with NaN3 being preferred. Typically, about 1-3 molar equivalents of the azide source are used. The reaction of step a is typically carried out in a solvent, such as DMSO/H2O, N,N-dimethylformamide, tetrahydrofuran, ethanol, methanol, and dioxane, preferably DMSO/H2O, at temperatures ranging from room temperature to about 80° C. In most cases, the resulting crude azide of Formula (2) can be used without further purification.

When D1 is methylene, compounds of Formula (1) in which X is a hydroxyl group can be directly converted to the azide. Such reactions are well known and appreciated in the art. For example, see Thompson et al., J. Org. Chem. (1993) 58: 5886-5888. In such reactions, the alcohol of Formula (1) is dissolved in a suitable solvent, such as toluene, benzene, tetrahydrofuran, or dioxane, with the preferred solvent being toluene, and the reaction of step a is carried out using a diphenylphosphoryl azide, followed by a suitable organic base, as described above, with the preferred base being 1,8-diazabicyclo[5,4.0]undec-7-ene. Typically about 1-3 molar equivalents of the azide source are used.

The reaction is carried out with an appropriate chloroformate agent, such as a C1-C6 alkyl (e.g., methyl, ethyl, propyl, butyl), aryl (e.g., phenyl), or benzyl chloroformate. Thus, Z is defined in compounds of Formula (4) as C1-C6 alkyl, aryl, or benzyl. Generally, the reaction proceeds at temperatures from about −78° C. to ambient temperature. The product of Formula (4) can be isolated and purified by techniques well known in the art, as described above.

For example, an appropriate ester of Formula (4) is dissolved in a suitable solvent, such as methanol, and is further treated with a suitable base, such as sodium hydroxide, to give a compound of Formula (5).

The reaction of step d, in which a carboxylic acid, such as that of Formula (5), is coupled with an appropriate amine, such as that of Formula (6), under standard peptide coupling conditions, is well known to the skilled artisan. Specifically, the amine and the carboxylic acid are coupled in the presence of a peptide coupling reagent, optionally in the presence of a catalyst. Suitable peptide coupling reagents include N,N′-carbonyldiimidazole (CDI), N,N′-dicyclohexylcarbodiimide (DCC), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC), and 1-(3-(1-pyrrolidinyl)propyl)-3-ethylcarbodiimide (PEPC). Suitable catalysts for the coupling reaction include N,N-[dimethyl]-4-aminopyridine (DMAP). All of the reagents are combined in a suitable solvent, typically dichloromethane, chloroform, tetrahydrofuran, dioxane, or diethyl ether, and are stirred for 1 to 72 hours at temperatures ranging from ambient temperature to approximately the reflux temperature of the solvent. The desired product may be isolated and purified by techniques described above. Such coupling reactions are well known and appreciated in the art (Larock, R. C., Comprehensive Organic Transformations, 2nd Ed., copyright 1999, John Wiley & Sons, pp 1941-1949).

In the compounds depicted in Scheme III, Z is C1-C6 alkyl, aryl, or benzyl.

Another variation for making compounds of Formula (I) is depicted in step g. In step g, the triazole ring of Formula (11), in which D2 is nitrogen, is made by reacting a beta keto ester compound of Formula (10), such as a beta keto C1-C6 alkyl or benzyl ester, with an azide of Formula (2).

The hydroxyl group of the compound of Formula (15) maybe readily converted to the corresponding halide, as shown in step j, to give a compound of Formula (16) wherein Y is a halide. Examples of reagents for this reaction include PCl5, POCl3, PBr3, POBr3, and thionyl chloride, with PCl5 as the preferred reagent either neat or in a suitable solvent such as dichloromethane, benzene, or toluene at a temperature between 0 and 100° C. The preferred method is reacting a compound of Formula (15) with PCl5 in toluene at 40-60° C. This type of transformation is well known and appreciated in the art. See Buckle, D. R.; Rockell, C. J. M. J. Chem. Soc., Perkin I, 1982, 627-630. Subsequent ester hydrolysis, as taught in step c, followed by amide formation, as taught in step d, gives compounds of Formula (18). As shown in step k, the halide of the compound of Formula (18) may be substituted by reaction with an appropriate nucleophile such as, but not limited to, primary amines, secondary amines, alcohols or thiols to further encompass compounds of the present invention to give the desired compounds of Formula (8).

In such reactions, the compound of Formula (18) is dissolved in a suitable solvent, such as DMF, THF, DMSO, and reacted with the appropriate nucleophile in the presence of a suitable base. Such bases include triethylamine, potassium carbonate, cesium carbonate or sodium hydride. The reaction is generally carried out at temperatures ranging from room temperature to 100° C. In some cases, the reaction may be carried out neat, using the nucleophile as solvent. The product of Formula (8) can be isolated and purified by techniques described above.

As depicted in Scheme II, a compound of Formula (8) can be transformed to a thiocarbonyl compound of Formula (9) by [2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide] (Lawesson's Reagent) or phosphorus pentasulfide, typically in a suitable solvent, for example, toluene, ethylene glycol dimethyl ether, benzene, pyridine, xylene, or tetrahydrofuran, preferably toluene.

Thus, tablets or pills may be coated with sugar, shellac, or other coating agents. A syrup may contain, in addition to the present compounds, sucrose as a sweetening agent and certain preservatives, dyes and colorings and flavors. Materials used in preparing these various compositions should be pharmaceutically pure and non-toxic in the amounts used.

For the purpose of parenteral therapeutic administration, the compounds of the present invention may be incorporated into a solution or suspension. These preparations typically contain at least 0.001% of a compound of the invention, but may be varied to be between 0.001 and about 90% of the weight thereof. The amount of the compound of Formula I present in such compositions is such that a suitable dosage will be obtained. The solutions or suspensions may also include one or more of the following adjuvants: sterile diluents, such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents, such as benzyl alcohol or methyl paraben; antioxidants, such as ascorbic acid or sodium bisulfite; chelating agents, such as ethylene diaminetetraacetic acid; buffers, such as acetates, citrates or phosphates; and agents for the adjustment of tonicity, such as sodium chloride or dextrose. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic. Preferred compositions and preparations are able to be determined by one skilled in the art.

The compounds of the present invention may also be administered topically, and when done so, the carrier may suitably comprise a solution, ointment, or gel base. The base, for example, may comprise one or more of the following: petrolatum, lanolin, polyethylene glycols, bees wax, mineral oil, diluents such as water and alcohol, and emulsifiers, and stabilizers. Topical formulations may contain a concentration of a compound of Formula I or its pharmaceutical salt from about 0.1 to about 10% w/v (weight per unit volume).

The compounds of Formula I are antagonists of NK-1 receptors. Furthermore, the compounds of Formula I selectively antagonize NK-1 receptors relative to other tachykinin receptors. The antagonist activity of NK-1 receptor antagonists may be determined by the methods below.

NK-1 Receptor Binding Assay

The IM-9 cell line is a well-characterized and readily available human cell line. See, e.g., Annals of the New York Academy of Science, 190: 221-234 (1972); Nature (London), 251:443-444 (1974); Proceedings of the National Academy of Sciences (USA), 71:84-88 (1974). These cells are routinely cultured in RPMI 1640 supplemented with 50 μg/ml gentamicin sulfate and 10% fetal calf serum.

The IM-9 cells are homogenized from cell pellets for crude membranes. The membranes are isolated by homogenizing tissue samples in 30 ml w/v with 50 mM Tris buffer (pH 7.4). After an initial spin at 900×g, the supernatant is transferred to a clean centrifuge tube and the membranes isolated by centrifugation at 38,000×g.

Approximately 25 μg of membranes are incubated with 0.2 nM [125I]-substance P (NEN, Boston, Mass.) in a receptor binding assay. The assay buffer contains 50 mM Tris, 3 mM MnCl2, 0.02% bovine serum albumin, 40 μg/ml bacitracin, 2 μg/ml chymostatin, 4 μg/ml leupeptin and 40 μg/ml thiorphan (pH 7.4). Binding studies are conducted in a final volume of 200 μl containing various concentrations of test compounds. Non-specific binding is determined by incubating some tubes in the presence of 1 μM substance P (Peninsula, Belmont, Calif.).

Binding is terminated 1 hour later by rapid filtration using a TOMTEC 96-well cell harvester (TOMTEC, Orange, Conn.) through GF/A filters that have been presoaked with 0.3% polyethyleneimine (Sigma, St Louis) for 1 hour. The filters are washed with 5 ml of ice-cold 50 mM Tris buffer (pH 7.4) and placed in a drying oven at 60° C. The dried filters are treated with MeltiLex A melt-on scintillator sheets (Wallac, Gaithersburg, Md.), and the radioactivity retained on the filters counted using the Wallac 1205 Betaplate scintillation counter. The results are analyzed using a Log-Logit plot from a Microsoft Excel™ workbook and converted to Ki values with the Cheng-Prusoff equation. Protein concentrations are measured using Coomassie® protein assay reagent (Pierce, Rockford, Ill.), with BSA for standards (Bradford, 1976).

Binding studies are carried out to evaluate the ability of compounds of the present invention to inhibit NK-1 receptor activation. Such studies provide in vitro data regarding the efficacy of the compounds of the present invention. Representative Examples of the compounds of Formula (I) were tested in the receptor binding assay described herein and were demonstrated to have binding affinities (Ki values) of ≦100 nM.

Several preclinical laboratory animal models have been described for a number of the disorders associated with an excess of tachykinins. One such in vivo assay, described below, may be used to determine whether NK-1 receptor antagonists are CNS-penetrant.

Gerbil Foot-Tapping

The gerbil foot-tapping assay is well recognized in the art. For example, see Rupniak et al., Eur. J Pharmacol. (1997) 326: 201-209.

Male Gerbils (Mongolian), weighing between 20-40 gm (Harlan Labs, Indianapolis, Ind.) are used for the experiments. Animals are allowed to acclimate prior to any testing.

An NK-1 receptor agonist, such as GR73632 (δ-Aminovaleryl [Pro9, N—Me-Leu10]-Substance P(7-11)) (Peninsula Labs), is dissolved in acidified saline (1 ml acetic acid in 1 liter of 0.09% saline) to make a 1 mg/ml solution (corrected for peptide content). The stock solution is further diluted to 10 μg/ml in saline (0.9% normal saline), aliquoted and kept frozen until use. The stock solution is further diluted to 3 pmol/5 μl in saline for i.c.v. injections.

Test compounds are formulated in appropriate vehicle to a concentration of 1 ml/100 gm body weight. Compounds are dosed by oral gavage (p.o.) or subcutaneously (s.c.) or intraperitoneally (i.p.) at pre-determined times prior to intracerebroventricular (i.c.v.) challenge of agonist. For i.c.v. administration, test compound is co-injected with agonist.

Free hand i.c.v. injection is performed by direct vertical insertion of a cuffed 27-gauge needle with a Hamilton 50 μl syringe, to a depth of 4.5 mm below bregma. Light anesthesia with isoflurane may be needed prior to the injection, but is not used routinely.

Following i.c.v. injection of agonist, animals are placed in a plexiglas observation box, and hind foot tapping events are counted for 5 minutes. Data collection is computerized.

Data are analyzed by ANOVA followed by Dunnett's test using JMP statistical program (IBM platform). Data are expressed as number of events/5 minutes.

The results of NK-1 receptor binding studies demonstrate the ability of compounds of the present invention to act as antagonists of NK-1 receptors. It is recognized that the compounds of the present invention would be expected to inhibit the effects of NK-1 receptor activation. Thus, the compounds of the present invention are expected to be useful in the treatment of various disorders associated with excess tachykinins, as described to be treated herein, and other disorders that can be treated by such antagonists, as are appreciated by those skilled in the art.

In one embodiment, the present invention provides methods of treating disorders selected from the group consisting of anxiety, depression, psychosis, schizophrenia and other psychotic disorders, neurodegenerative disorders (including senile dementia of the Alzheimer's type, Alzheimer's disease, AIDS-associated dementia, and Down's syndrome), seizure disorders (including generalized and partial seizures), demyelinating diseases (including multiple sclerosis and amyotrophic lateral sclerosis), neuropathological disorders (including peripheral neuropathy, diabetic and chemotherapy-induced neuropathy, and post-herpetic and other neuralgias), acute and chronic obstructive airway diseases (including adult respiratory distress syndrome, bronchopneumonia, bronchospasm, chronic bronchitis, drivercough, and asthma), inflammatory diseases (including inflammatory bowel disease, psoriasis, fibrositis, osteoarthritis, and rheumatoid arthritis), disorders of the musculo-skeletal system (such as osteoporosis), allergies (including eczema and rhinitis), hypersensitivity disorders (such as poison ivy), ophthalmic diseases (such as conjunctivitis, vernal conjunctivitis, and the like), cutaneous diseases (including contact dermatitis), atopic dermatitis, urticaria, other eczematoid dermatites, addiction disorders (including alcoholism), stress-related somatic disorders, reflex sympathetic dystrophy (such as shoulder/hand syndrome), dysthymic disorders, adverse immunological reactions (such as rejection of transplanted tissues), disorders related to immune enhancement or suppression (such as systemic lupus erythematosis), gastrointestinal disorders, diseases associated with the neuronal control of viscera (such as ulcerative colitis, Crohn's disease and irritable bowel syndrome); disorders of bladder function (such as bladder detrusor hyper-reflexia and incontinence), atherosclerosis, fibrosis and collagen diseases (such as scleroderma and eosinophilic fascioliasis), irritative symptoms of benign prostatic hypertrophy, disorders associated with blood pressure (such as hypertension), disorders of blood flow caused by vasodilation or vasospastic diseases (such as angina, migraine, and Reynaud's disease), emesis (including chemotherapy-induced nausea and acute or delayed emesis), and pain or nociception (including that attributable to or associated with any of the foregoing conditions), comprising: administering to a patient in need thereof an effective amount of a compound of Formula I or a pharmaceutical composition thereof. That is, the present invention provides methods of treating disorders associated with an excess of tachykinins, comprising: administering to a patient in need thereof an effective amount of a compound of Formula I or a pharmaceutical composition thereof.

The present invention contemplates the various disorders described to be treated herein and others that can be treated by such antagonists, as appreciated by those skilled in the art.

The disorders associated with an excess of tachykinins are treated by administering an effective amount of a compound or pharmaceutical composition of Formula 1. An effective amount can be readily determined by the attending diagnostician, as one skilled in the art, by the use of conventional techniques and by observing results obtained under analogous circumstances. In determining an effective amount, the dose of a compound of Formula I, a number of factors are considered by the attending diagnostician, including, but not limited to: the compound of Formula I to be administered; the species of mammal—its size, age, and general health; the specific disorder involved; the degree of involvement or the severity of the disorder; the response of the individual patient; the mode of administration; the bioavailability characteristics of the preparation administered; the dose regimen selected; the use of other concomitant medication; and other relevant circumstances.

An effective amount of a compound of Formula I is expected to vary from about 0.001 milligram per kilogram of body weight per day (mg/kg/day) to about 100 mg/kg/day. Preferred amounts may be readily determined by one skilled in the art.

Of the disorders associated with an excess of tachykinins that are treated according to the present invention, the treatment of depression, anxiety, inflammatory bowel disease, irritable bowel syndrome, and emesis (chemotherapy-induced nausea and acute or delayed emesis) are particularly preferred.

Thus, in a preferred embodiment, the present invention provides a method for treating a depressive disorder, including major depressive disorder, comprising: administering to a patient in need thereof an effective amount of a compound of Formula I or a pharmaceutical composition thereof.

In another preferred embodiment, the present invention provides a method for treating anxiety, including generalized anxiety disorder, panic disorder, and obsessive-compulsive disorder, comprising: administering to a patient in need thereof an effective amount of a compound of Formula I or a pharmaceutical composition thereof.

Disorders of the central nervous system, including depressive and anxiety disorders, have been characterized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV™) (1994, American Psychiatric Association, Washington, D.C.). The DSM-IV™ provides clear descriptions of diagnostic categories. The skilled artisan will recognize that there are alternative nomenclatures, nosologies, and classification systems for these disorders, and that these systems may evolve with medical scientific progress. For instance, the ICHPPC-2 (International Classification of Health Problems in Primary Care) (3rd edition, 1983, Oxford University Press, Oxford) provides an alternative classification system. Thus, the terms “depression,” “depressive disorders,” “anxiety,” and “anxiety disorders” are intended to include like disorders that are described in other diagnostic sources.

According to the fourth edition of the DSM-IV™, major depressive disorders are characterized by one or more major depressive episodes, which consist of a period of at least two weeks of depressed mood or loss of pleasure, in addition to other symptoms. Thus, the skilled artisan will recognize that the present invention is useful for the treatment of either a single episode or recurrent episodes of major depressive disorder.

The skilled artisan will appreciate that other depressive disorders may also be treated by administering an effective amount of a compound of Formula (I). Such other depressive disorders include dysthymic disorder, and depressive disorders not otherwise specified (for example, premenstrual dysphoric disorder, minor depressive disorder, recurrent brief depressive disorder, or postpsychotic depressive disorder of schizophrenia). In addition, the treatment of depression by the compounds of Formula (I) may also include the treatment of mood disorders due to a general medical condition and substance-induced mood disorders.

The DSM-IV™ also provides a diagnostic tool for anxiety and related disorders. These disorders include: panic disorder with or without agoraphobia, agoraphobia without history of panic disorder, specific phobia, social phobia or social anxiety disorder, obsessive-compulsive disorder, post-traumatic stress disorder, acute stress disorder, generalized anxiety disorder, anxiety disorder due to a general medical condition, substance-induced anxiety disorder and anxiety disorder not otherwise specified. As used herein, the term “anxiety” includes treatment of those anxiety disorders and related disorders described in the DSM-IV.
